I did now with 4.3.0-rc6 and there is the same problem.
I reattached the two outputs, before and after (as a patch) suspend-to-ram:
diff -u alsa-info.txt.4.3-rc6.before alsa-info.txt.4.3-rc6.after >
alsa-info.txt.4.3-rc6.patch
OK, so we need to hunt more.
Kailang, could you check whether anything missing for this codec?
The symptom appears like the COEF thingy you fixed by extra init
verbs.
thanks,

After a fresh reboot, the sound works ok but if I put the computer to
sleep (pm-suspend), after it wakes up there is no sound anymore.
I did try 'alsa force-reload' after suspend but still no sound.
After 'pm-hibernate' sound is back again.
I found an old thread here:
https://bugzilla.kernel.org/show_bug.cgi?id=49421 where Michael seems
to have the same problem which is still unsolved; maybe I can help
with more info.
I attached the 'alsa-info.sh' output before and after suspend:
'alsa-info.txt.before' and 'alsa-info.txt.after' (as a patch to stay
below 80k mail size rule: diff -u alsa-info.txt.before
alsa-info.txt.after > alsa-info.txt.patch)
The only difference between before and after is this one:

but the 2y older version with no touch
If I boot into windows (8.1) everything works great, including sound
(even after suspend)
Did you test with 4.3-rc kernel?  3.19 is very old.
It's likely codec-specific stuff, as there is no difference seen in
alsa-info.sh outputs (the converter is the value assigned dynamically
at playback, so it doesn't matter at all).
